MAGHINE Eon BENDING EELLIES.

Speccation of`Letters Patent No. 11,209, dated July 4, 1854:.`

To all whom t may concern Improved Machine for Bending Fellies; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specilication, Figure l being a side elevation of the machine, in the position which it assumes when afelly is about half bent; Fig. 2, a longitudinal vertical section thereof `through `the center; Fig. 3, a transverse vertical section of the same in the line ai of Fig. l; Fig. 4, a

horizontal section of the machine, inthe line y y of Fig. l, b-ut in a position when the bending is nearly completed; Fig. 5, a horizontal Section thereof in the line' y y, of Fig. l in the position which it assumes just at the momentof completing the bending of a felly; Fig. G, a plan of the machine, a portion of the frame being broken away, to show certain parts beneath, and Fig. 7 a rear view of the upright portion of the frame and parts attached thereto.

Like letters designate corresponding parts in all the ligures.

The nature of my invention consists, lirst, in the combination of the vibrating felly mold B, with the flanged bending wheel M, arranged and operating substantially as hereinafter specified; secondly, in the manner of perfectly bending the last end of each felly and securing it when completely bent, upon the mold, viz., by the combined action of the bending wheel M, and of the Wedge -clamp g, constructed and operating substantially as hereinafter set forth,

The parts of the machine are mounted in a frame A, consisting essentially of bottom` and top horizontal `beams connected by a vertical post, in the manner represented. In the two horizontal beams are slots I, I, for the reception of sliding plumber blocks H, I-I, which bear the shaft C, `of the felly mold B. The plumber blocks are respec tively provided with corresponding series of holes a, a, &c., through which pins b, pass and also through holes in the frame, whereby the position `of the shaft may be changed so as to bring different sizes of molds always at the proper distance from the bending wheel M.

The felly mold B, is composed of a cylindrical case, built upon suitable framework,

` andextending in circumference, as far as Be it known that I, THOMAS Cox, of Lan caster, in the county of Lancaster and State `of Pennsylvania, have invented anew and necessary to bend any portion of the whole felly desired` Its diameter depends upon thesize of Wheel to be made, and its length on the thickness and number of fellies to be bent at one time. It is arranged so as to be readily attached to, and removed from the shaft C, by any convenient means,"such as the keys a, rl, passing through slots inthe mold-frame and through ears e, e, which projectfrom said shaft, as represented in the drawings. C i

j A tackle G, may be employed for raising and lowering the felly mold to and from its place on the shaft, as shown in Fig. l; It is operated `by means ofa lever E, inserted in the shaft C, and itsmovements, in both directions, `are limited by projections lv, o, upon it, striking a stop u, on the frame A.'

The bending wheel M, consists of a cylindrical portion m, of suitable thickness and diameter, and of a flange Z, projecting from the upper edge of the cylindrical portion. This bending wheel is mounted, on a vertical shaft, in a strong carriage D, which slides in ways vertically upon the upright post of the frame A, substantially as shown Vin the drawings. Said carriage is provided with a vertical rack n, which plays into a pinion y), (Fig. 3,) on Whose shaftr, is secured a crank, or hand-wheel, N, for the purpose of raising or lowering the bending wheel when and where desired. In order to retain said binding wheel in any position, a vibratory tightening lever S, is arranged upon the back of the frame post, so that its upper end may be caused to bear against and bind the shaft r, by pressing against its lower end; which can conveniently be done by means of a loop t, and key s, arranged as distinctly shown in Fig. 7

To bend a felly, the mold B, is brought i position, by tightening the lever S, if its own weight is not sufficient for the purpose. The mold is then turned so as to bring every part of its periphery successively opposite to the binding wheel, which consequently bends the felly piece `closely upon said mold,

in the manner indicated in Fig. 6, where about one half of a telly piece is represented as already bent; and at the same time the flange Z, holds the telly down in its proper place. Then, just beforethe lbinding wheel reachesthe last end of the elly, a cla-mpg, which consists essentially of ashankwith a slot in it, near one end, for the insertion of a key 71 and a wedge-shaped prong projecting at right angles from the other end thereof, (as shown in Figs. 4, 5, and 6,) is held by the hand against the unbent end of the felly in the position shown in Fig; 4. lVhile thus situated, its prong is pinched between the bending Wheel M, and the telly, and thus powerfully wedges the end of the felly against the mold and bends it perfectly thereon quite to the end, as shown in Fig.' 5. Finally, a'key h, is driven through the clamp between the case of the mold and a vertical .bar c', situated a little distance therefrom yis illed with bent fellies a, a&c. It is then removed from the machine and laid inside until the fellies become perfectly set; in the meantime, other molds being substituted and lledin the same way.

Having thus fully described my improved machine for bending fellies, what I claim therein as new and desire to secure by Let-- ters Patent, is f l. The combination of the Vibrating telly mold B, with the flanged bending wheel M, arranged and operating substantially as herein described.

2. I also claim the manner of perfectly bending the last end of each telly and securing it when completely bent, upon the mold, viz, by the combined action of the bending wheel M, and of the wedge-clamp g, vconstructed and operating substantially as here,- in set forth.

The above specification of my improved machine for bending the fellies of wheels signed and witnessed this 3rd day of May,
